Revamped Vapor & Engine Experiments | Update 22.2

April 18: 22.2.1 & 22.2.2 address a Mac-specific issue that caused crashes while using the Add panel. Known Mac issue: loading “Solar System Planets, Moons, and Large Objects” simulation sometimes results in a crash.

This update adds improved vaporization effects that are more accurate and colorful. It also introduces an experimental version of our new physics system that makes gravity simulation faster, more stable, and more accurate. We’d love it if you tried it out and helped us test it!

Please remember this system is still experimental. If you experience any problems, let us know! You can report any issues on our forums (local forum | Steam forum) or via Home > Send Feedback.

There are also dozens of smaller improvements and fixes. Here are some of the highlights:

Added Fahrenheit as a temperature unit

Added Filipino to available languages

Improved Search in Open panel

Trails & orbits work on older hardware again

Object lighting on Linux works again

New simulation with all planets, moons, and large Solar System objects

We’re excited for the upcoming official release of this new physics system so that everyone can enjoy the improvements to performance and accuracy. We’re also working on brand new galaxies and, while we had a setback with Surface Grids & Lasers, we are now making good progress again. Learn more about our progress on these features

Nice release! I love the new vapor system and the new physics system. There is just one small problem. Every few seconds there is a lag spike. For example the game would be running at 100 fps (which is what it normally runs at for me) but for 1 frame it drops to like 40 fps. This gets really annoying, if you can fix this that would be amazing!
